The ray XZ is the angle bisector of ∠WXY and m∠WXY = 105°. Enter m∠WXZ. The measure of ∠WXZ is
Answers
Answer:
∠WXZ = 52.5
Step-by-step explanation:
Angle Bisector is the line that divides that angle into two equal parts.
Hence, Ray XZ divide the ∠WXY into two equal parts.
⇒ [tex]\angle WXZ = \frac{1}{2} \angle WXY [/tex]
∴ [tex]\angle WXZ =\frac{1}{2}\times105^{\circ}=52.5[/tex]
⇒ ∠WXZ = 52.5
An angle bisector divides an angle into two equal parts.
The measure of [tex]\angle WXZ[/tex] is [tex]52.5^o[/tex]
Given that:
[tex]XZ \to[/tex] Bisector of [tex]\angle WXY[/tex]
[tex]\angle WXY = 105^o[/tex]
This means that:
[tex]\angle WXY = 2 \times \angle WXZ[/tex]
So, we have:
[tex]105^o = 2 \times \angle WXZ[/tex]
Divide both sides by 2
[tex]52.5^o = \angle WXZ[/tex]
Rewrite as:
[tex]\angle WXZ = 52.5^o[/tex]
Hence, the measure of [tex]\angle WXZ[/tex] is [tex]52.5^o[/tex]

A number and it's absolute value are equal. If you subtract 2 from the number, the new number and it's absolute value are not equal. What do you know about the number? What is a possible number that satisfies these conditions?
Answers
The absolute value is the distance away from 0 the number is.
So 1's absolute value would be 1, yet -5's absolute value would be 5.
So the number that's equal to its absolute value is positive, and the one that's not is negative.
So if you subtract 2 from the positive number, it must turn negative.
So 1 is a number that satisfies these conditions.

Jenny charges for delivering the cakes.
Bob lives 12 miles away.
How much will Jenny charge to deliver the cakes? delivery charges £4 mixed cost + 60p per mile
Answers
To deliver the cakes to Bob, Jenny will charge £11.20.
Explanation:To calculate the delivery charges, we need to find the distance between Jenny's location and Bob's location. Since Bob lives 12 miles away, the delivery distance will be 12 miles. Jenny charges £4 as a mixed cost plus 60p per mile. So, the delivery charge will be £4 + (12 miles * 60p) = £4 + £7.20 = £11.20.

What is Unitary method?It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Steps to Use Unitary MethodFirst, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.
Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.
Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.
Given:
riding at a rate of 9 miles per hour

A rational number can be written as the ratio of one blank to another and be represented by a repeating or blank decimal. What are the two vocabulary for this sentence?
Answers
The answer is a rational number is one integer divided by another, and can be represented in either decimal of fraction form. The explanation behind this is visualize you are using long division to divide one number by one more. You divide, and then you acquire a remainder. Then you carry down a zero (multiply by ten) and divide again. Well, there are only so many balances you could perhaps have. For example, for 5, your choices are 0, 1, 2, 3, and 4. Sooner or later, you will replicate a remainder, at which fact you will just keep dividing the same method you did last time you saw that remainder -- and that's the reason why it repeats.

From a rectangular piece of cardboard having dimensions a × b, where a = 20 inches and b = 70 inches, an open box is to be made by cutting out an identical square of area x2 from each corner and turning up the sides (see the figure). Express the volume V of the box as a function of x.
Answers
The volume of the box as a function of x will be 1400x - 180x² - 4x³.
First and foremost, you should note that the volume of a rectangular prism is given as:
= Length × Width × Height
where,
Length = 70 - 2x
Width = 20 - 2x
Height = x
Volume = Length × Width × Height
Volume = (x)(20 - 2x)(70 - 2x)
Volume = 1400x - 40x² - 140x² + 4x³
Volume = 1400x - 180x² - 4x³
Therefore, the volume of the box as a function of x will be 1400x - 180x² - 4x³.

Answers
x² + 24x = 17 (1)
Note that
(x + 12)² = x² + 24x + 144
By adding 144 to the left side of equation (1), it becomes a perfect square.
Therefore
x² + 24x = (x+12)² - 144 (2)
Substitute (2) into (1).
(x + 12)² - 144 = 17
(x + 12)² = 17 +144
